NEMIX RAM 768GB DDR4 ECC RDIMM Kit

This 768GB kit contains six 128GB registered DIMMs built for enterprise servers and workstations that require error-correcting memory. It targets IT professionals managing virtualisation clusters, large databases or high-density compute nodes where maximum capacity per channel is essential.

2933 MT/s CL21 with 4Rx4 organisation

Each module runs at DDR4-2933 (PC4-23400) with CAS latency 21 at 1.20V. The quad-rank x4 layout delivers the full 768GB across six slots, but consumes more electrical loads per channel than dual-rank alternatives, limiting maximum DIMM-per-channel populations on some platforms.

288-pin registered design without heat spreaders

Registered buffering reduces electrical load on the memory controller, enabling the high module count in this kit. The bare green PCB fits tightly spaced server DIMM slots where tall heat spreaders would interfere with airflow or adjacent components. Modules use major OEM DRAM from Samsung, Micron or Hynix and are stress-tested before shipment.

Questions about this item

Will the 4Rx4 organisation of these 128 GB DDR4 modules work with the registered DIMM slots in my current server board?

Each module is a 288-pin DDR4 RDIMM with 4Rx4 organisation and ECC; the memory controller must support 4-rank registered DIMMs at 1.2 V for the kit to be recognised.

How can I verify the kit is running at the rated 2933 MT/s with ECC active after installation?

Enter the firmware memory information screen and confirm the speed reads 2933 MT/s (PC4-23400) and that ECC status shows enabled for all six modules.

What exactly ships in the box and are any extra parts required for installation?

The package contains six 128 GB DDR4 2933 CL21 ECC RDIMM modules; no heat spreaders, cables or additional hardware are included.
